Question

Which of the following best compares the structure of carbohydrates and nucleic acids?

A. Carbohydrates consist of monomers of carbon, hydrogen, and oxygen, while nucleic acids consist of monomers of a sugar, a phosphate group, and a nitrogenous base.

B. Carbohydrates have four rings containing carbon, hydrogen, and oxygen, while nucleic acids have subunits containing an amino acid and a phosphate group.

C. Carbohydrates contain carbon, hydrogen, and oxygen and have a hydrophobic end and a hydrophilic end, while nucleic acids contain a carbon backbone, a side change, and an amino group.

Answer 1

The most appropriate answer is A. Both carbohydrate and nucleic acids are polymers with Carbohydrate being a long chain of repeated monomers of carbon, oxygen and hydrogen bonded while the nucleic acid is made up of repeating structures of sugar, phosphate and nitrogenous base groups.
